How many twins/triplets/multiples have you met?

I was thinking about my school days, and I realised that I went to school with a lot of twins/triplets. At junior school, there were two sets of triplets - Joe, Rosie and Lydia, and Jade, Sophie and Mitchell. There was also quite a few twins, but not in my classes, so I don't recall their names. Then, in sixth form, there we three sets of twins - Rowan and Levi (identical boys), Joe and Nick (fraternal boys), and Martin and Georgia. So, how many twins have you met?
